PROCESS FOR STRAIGHIENING BUGS.

Application filed August 16, 1926. Serial No. 129,636.

This invention relates to an improved process for straightening orcorrecting inequalities in the shape of floor rugs, particularlyoriental rugs. Many oriental rugs are misshapen in several ways, some ofthese rugs are shorter on one edge than on the edge which is oppositelydisposed thereto; sometimes the difference in length amounting toseveral inches; they are also curled at the edges, up or down, more orless, so that they will not lie flat upon the floor.

Efforts have been made to overcome these deficiencies and to correct theshape of the rugs so that they will lie flat and have their oppositelydisposed edges of the same length. One process for attempting to arriveat this result has been to mark the correct shape and size of the rug ona floor or board and then, by means of hand pliers, to stretch the ruguntil it assumes the dimensions of the shape thus marked out, the edgeof' the rug being tacked to the floor or board, and then thoroughlywetting the rug with water and sometimes with starch.

The result attained by this latter process is merely to straighten thefibers of wool in the rug, and when the rug is again exposed to anydampness, the threads returnto their original shape and the rug againbecomes misshapen. This old process also takes a long time for the rugto dry when it is lying in contact with and tacked down to the floor.

The object of this invention is toovercome the difficulties hereinbeforeencountered'and to straighten the rug so that it will remain permanentlystraight and lie flat upon the floor.

The invention therefore consists in the process of straightening a rughereinafter described and particularly pointed out in the claim.

The preferred form of apparatus for strai htening the rugs by myimproved process is illustrated in the accompanying drawin gs in whichFigure 1 is a plan view of the apparatus, a rug after having beenstraightened being shown in dotted lines in connection therewith. i

2 is a front elevation of the said apparatus partly broken away andshown in section. T

Fig. 3 is a plan view of a rug, one edge of which is shorter than theother and illus-, trates one form of misshapen rug which can bestraightened by my improved process utilizing the apparatus disclosed inFigs. 1 and 2. I

Like numerals refer to like parts in the several views of the drawings.

In the drawings, 5 and 6 are longitudinal members of the apparatus and 7and 8 are cross members thereof. The cross member 71s provided with agroove 9 extending longitudinally thereof, in which is positioned a bar10 which clamps one end of a. rug 11. in the, groove 9, pressure beingapplied to the barto perform the clamping operation by a usual form.of-C clamp 12 consisting of a frame 13 and screw 14 havinga swivel 15which bears upon, the clamp bar 10, the end 16 of the frame bearingagainst the under side of the cross member 7. i

In the drawings there are two of the clamp members shown in connectionwith the cross member 7, but it is evident that as many of tlfi C clampsmay be utilized as may be desira e. i

Brackets 17 are fastened to the underside of the cross member 7,adjacent its opposite ends and are supported by and have screwthreadedengagement with adjusting screws 18 which are rotatably mounted at theiropposite ends in brackets 19, two of which are fastened to each of thelongitudinal members 5 and 6. Each screw 18 is provided with a handle20, by which it may be rotated and thus move the cross member 7 towardor away from the cross member 8 in order to stretch the rug is a mannerhereinafter more particularly described.

The cross member 8 has pins 21 and 22 adjacent its opposite ends andprojecting downwardly therefrom into holes 23 and 24 in the longitudinalmembers 5 and 6, which are provided with graduations 23' and 24, wherebythe cross member 8 can be approximately positioned according to thelength of the rug which is to be stretched. The cross member 8 isprovided with a clamping bar 25, which is positioned in a groove 26vextending longitudinally of the .cross member 8, which is adapted toclamp one end of the rug 11 in the groove 26 by means of the C clamps 27which are of the same construction as the C clamps 12.

The misshapen rug illustrated in Fig. 3 embodies a short side 28, anoppositely disposed longer side 29 and ends 30 and 31. The processwhereby this rug may be
